Air War: US and Europe Clash Over Proposed Carbon Reductions for Airlines
22.05.12
Depending on the calculations, air travel accounts for perhaps 3 to 5% of global carbon dioxide emissions, far below sources like deforestation, coal-fired electricity and automobiles. Yet I’ve always thought that airplanes play an outsized symbolic role in climate change—and in the challenge of actually stopping it. You can substitute coal for renewables or nuclear, and trade in your gas-guzzling SUV for an plug-in hybrid—in both of those cases, technological alternatives do exist, even if they’re more expensive.
But there’s really no immediate alternative to carbon-intensive jet fuel. Airlines have experimented with biofuel mixes , but they’re still a long way from regular use. Right now the only means to reduce emissions from air travel—aside from improving engine and operational efficiency —and that’s to fly less. The airline industry expects 3.3 billion travelers by 2014 —up more than 800 million from 2009—with much of the growth occurring in the booming Asia-Pacific region. Whether it’s visiting Grandma for the holidays or jetting to Shanghai for business, every indication is that we’ll keep flying—and emissions will keep growing.
